The data on melanoma associaed with melanocytic nevus are controversial. A longitudinal prospective study of 107 cases of cutaneous melanoma revealed that 9 (8.4%) cases were presumed to be linked to a precursor lesion, but only in 1 (0.9%) out of these cases the histopathological examination showed an associated melanocytic nevus. The vague information of a preexisting lesion of cutaneous melanoma is not sufficient to consider it a tumour precursor and it requires histopathological evidence to confirm the diagnosis.
与黑素细胞痣相关的黑色素瘤数据存在争议。一项对107例皮肤黑色素瘤的纵向前瞻性研究表明,9例(8.4%)被推测与前驱病变有关,但其中只有1例(0.9%)经组织病理学检查显示存在相关的黑素细胞痣。皮肤黑色素瘤既往病变的模糊信息不足以将其视为肿瘤前驱病变,需要组织病理学证据来确诊。
